 lJ-21 in, long, J-2 lin. broad, linear or linear-lanceolate, acute and 

 mucronate at the apex, shortly cuneate at the sessile or subsessile base, 

 revolute at the margins, with a very prominent acute or almost wing-

 J- 1 in. long, 2-4: lin. broad, ovate-lanceolate to subcordate-ovate, acute 

 or acuminate and mucronate, rounded or abruptly contracted into a 

 distinct broad petiole, otherwise as in the leaves. Involucre solitarv, 

 .sessile, 2 lin. long, 2J lin. in diam., campanulate, glabrous outside and 

 within, with 4 glands and 5 subquadrangular oblong or ovate toothed 

 lobes; glands about § lin. in their greater diam., compressed-funnel- 

 shaped when viewed from the back, shallowly concave and transversely 

 oblong when viewed from above, entire. Capsule erect, :U-4 lin. in

52. E. verticillata. Pax in BuU. llerh. Boiss. vi. 740. Rootstock 

 a tuber, producing 1 or more annual stems 4-9 in. high, branching into 

 a 3-rayed umbel at the top and with 1-2 pairs of opposite branches (or 

 a whorl of them, Pax) below, glabrous. Leaves opposite, whorled at 

 the base of the umbel, sessile, subcoriaceous, J-IJ in. long, 2-7 lin. 

 l)road, with the basal pairs very much reduced or scale-like, lanceolate or 

 elliptic, acute, rounded or narrowed at the base, glabrous on both sides. 

 Branches and rays of the umbel 2-2|- in. long, once-forked, glabrous. 

 I>racts 0-10 lin. long, 4-G lin. broad, sessile, ovate, acute. Involucres 

 solitary, sessile, lJ-2 lin. in diam., glabrous (pubescent, Pax)^ with 4 

 glands and 5 oblong truncate toothed lobes; glands £ lin. in their 

 greater diam., transversely oblong, concave, entire. Ovary glabrous, 

 exserted on a recurved pedicel ; styles | lin. long, free to the l)ase, not 

 spreading, l)ifid at the apex. Capsule about 2 lin. in diam. and rather

I have not seen the type of this species, hut describe from DekiucU's specimen, 

 whicli is named E. veriicillata by Pax himself, and aj^-rees with theori-^inal descrip- 

 tion except that the stem does not bear 2 whorls of branches and the involucres are 

 not surrounded by 4 bracts and are glabrous. The presence of 4 bracts surrounding 

 one involucre in tlie type suggests that it is abnormal, as no Enphorhia I have 

 examined has been found to have 4 bracts to tlie same involucre. 



53. E. platycephala, Pax hi Engl. Jahrh. xix. 122. Bootstock 

 an elongated fleshy tuber 1| in. (or more?) thick, producing 1 or more 

 annual erect stems 3-4 in. high and J-J in, thick at the base, with an 

 umbel of 3-4 rays at the apex, glabrous. Leaves sessile, alternate, 

 whorled at the base of the umbel, l|-3 in. long, ]-| in. broad, narrowly 

 lanceolate to cuneate-oblanceolate, acute, entire, glabrous on both sides.
